Heat Pump Installation in Johannesburg & Gauteng

Sizing, plumbing, electrical and commissioning for new heat pump plant.

A heat pump installation is only as good as its sizing and pipework. We size on measured or calculated daily hot water demand and peak draw-off rather than on tank volume alone, then set up stratification, recirculation and control so the unit spends its time in its efficient operating band.
